TALKBNG-MACHINE.

To all whom it may concern.-

- Be it known that 1, CHARLES THOMAS, a

subject of the King of England, residing at Newton Abbot, Devon, England, have invented new and useful Improvements in Talking-Machines, of which the following is a specification.

My invention has for its object the provision of certain mechanical devices which will enable a grainophone or disk-recording -maohine to be readily used for producing phonograph or cylinder records.

- The accompanying drawings show how I carry the invention into eil'ect.

Figure 1 is a perspective view of a combined gramophone and phonograph rovided with a frame carrying the horn an an Edison worm. Fig. 2 is a side view of the turn-table. Fig. 3 is a perspective view of a record-disk. Fig. 4 shows a separate view of the frame. q 7

Similar letters refer to similar parts throughout the several views.- I

With the object in view I take an ordinary gramophone provided with the usual case a containing the internal driving mechanism, .a cover a, and record-disk b. To the turntable 0 is fixed a stem having a screw-thread ed outer end, to which the mandrel d is secured, so that the latter is operated direct by and with the turn-table.

[The mechanism which enables me to usethe same horn'e and an appropriate sup orttherefor without removing any parts rom or attaching same to the apparatus for operating with a dish or a cylinder consists of a frame constructed of two standards f f,

fitted with an Edison worm g and a guidespindle 7b. The horns is fitted with asleeve e, capable of sliding along the spindle h. Connected with said sleeve is an arm 'i, whose free end i is formed into a screwthreaded claw to mesh with the worm g and be driven thereby, the worm receiving motion' from the turn-table a through the in; tervention o f pulleys k and Z and driving strap 'm. The frame is mortised in the open lid a of the box, and the guide-spindle 72v projects into a hole in the top of the box a. The standard f is disposed underneath the turntable.

For use as a phonograph the apparatus is turned on edge, as indicated in Fig. 1, so as to place the cylinder in a horizontal position. The horn. e and its arm 11 are so ad justed as to insure the necessary contact of the recorder or reproducer with the cylinder. For further security I connect the'repreducer with the horn by a rubber sleeveor socket e.

. When using the apparatus as aJgmm-H phone, the box a is placedjin'its normal "osi tion, the strap m is thrown oftafiathe s eeve of the horn is allowed to come on tdtheinner faceof the standard 1 whileth e claw i is ducer is then adjusted u'popthe face of, the disk. It is to be mentioned that the sleeve e is of such a length as to'suit the position of the reproducer on the disk'i I am aware that prior to my invention, convertible phonographs and have been made, but the mec vided for the purpose consisted of separate Igramophones amsms' pros or additional means that required detach ing and readjusting in diflerenti positicns for use with each. type of apparatus, b my invention the same. parts will" throughout in SubSl78,Ill/l&lly"; tion, the distinguishing feature, beingth the mechanism in its normal position sex as gramophone, but being convertedfor use as a honograph by standin an edge; 1 I; there ore do not claim the com ination-ofjth'e two types of machine broadly; but

What I do claim as my Jnvention,and (le sire to secure by Letters Patent of the United States, is

i. A convertible gramophone andphono graph comprising a gramophone turn-table,

a spindle upon which said turntable rotates, a phonograph-mandrel detachably mounted upon said spindle, a reproducer for operation relatively either of said parts and means for feeding said reproducer, as set forth.

l 2. .ln a convertible'gramo honeand phonograph, the combination wit a gramophone turn-table, its spindle and detachable honegraph-mandrel mounted on said spind e, of frame comprising two standards secured "in the cover of the phonograph-box, an Edison -wor1n journaled in sai; standards, a guidehe same spindle fixed in the standards, a horn having I name to this specification in the presence of a1 sleeve IFOUIltBd onI said glide-spindie,1 a two subscribing Witnesses. c aw-arin est on the 10m an engaging t 1e Edison Worm, a reproducer at the end ofthe CHARLES THOMAS 5' horn, and gear for driving the Edison Worm from the turn-table, as set forth.

In testimony whereof I have signed my Witnesses:
